BOKA TOPAZ against its type
Built in 2007, it is 4 years older than the median offshore vessel on this register, which was built in 2011 (410 vessels with a known build year). At 8,009 gross tonnage it is larger than 79% of the other 396 offshore vessels with a recorded tonnage. It is one of 70 offshore vessels here under the Norway flag, 16.9% of the 413 on the register. The same builder is recorded for 20 other vessels here, one of them an offshore vessel.
Its 3,632 t of CO₂ for 2025 is 10% below the median of 4,049 t among the 390 offshore vessels on this register that reported for 2025. Per nautical mile it emitted 912.5 kg CO₂, 2.6 times the type median of 348.3 kg. It logged 2,126 hours at sea against a median of 3,550 hours for its type that year. 4.1% of its 2025 emissions were at berth; the median for offshore vessels was 6.4%. The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.
